However, the use of unactivated alkyl halides as radical precursors remains far less developed. Here, we report a photoreductive -heterocyclic nitrenium-catalyzed radical-polar crossover for the 1,2-dicarbofunctionalization of alkenes by using unactivated alkyl and aryl iodides. These reactions can be carried out under simple, transition-metal-free conditions with easily obtainable materials such as alkyl/aryl halides, alkenes, and aldehydes. The reactions exhibit a broad range of substrate compatibility and good tolerance towards functional groups. This approach offers a new tool to unlock the compatibility of carbon skeletons.","PeriodicalId":12794,"journal":{"name":"Green Synthesis and Catalysis","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140148085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent years have witnessed a growing focus on the efficient synthesis of chiral amines. Transaminases, as catalysts, have emerged as green, efficient, and highly selective solutions for substrates containing ketones or aldehydes, demonstrating exceptional performance in the synthesis of active drug molecules and natural products. This review primarily centers on the application of transaminases in the synthesis of important drug molecules bearing chiral amine group on acyclic or cyclic backbones. We delve into specific examples, highlighting the catalytic prowess of the sole transaminase catalyst as well as the combination with other enzymes in cascade transformations. This review illustrates the primary challenges that transaminases face and provides practical solutions that have been developed in these contexts. These solutions encompass various strategies and techniques that enhance the applicability and efficiency of transaminase-catalyzed reactions. In closing, we offer an outlook on the future of transaminase applications, discussing potential developments and emerging areas where this green and selective catalysis may play a pivotal role.","PeriodicalId":12794,"journal":{"name":"Green Synthesis and Catalysis","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140148130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we performed DFT calculations to delve into the multifaceted mechanistic details of glycosylation reactions, including the equilibria among reactive glycosyl triflate intermediates in solution, the stereoselectivity imparting protecting groups, solvent effects, base, and the anomeric effect. Our results provided theoretical corroborations to 2-OAc neighbouring group participation (NGP), the arming/disarming effect, the coordination theory of solvent effect on glycosylation stereochemistry, and the influence of solvent polarity on the reaction kinetics spanning the S1-S2 continuum. For the first time, the existence of putative contact-ion-pairs (CIP) of glycosyl oxocarbenium and triflate anion in organic solutions was theoretically confirmed with the identification of multiple ground state structures employing an implicit Solvation Model based on Density (SMD). Kinetics of nucleophilic attack of model glucosyl triflates by simple alcohol acceptors ethanol (EtOH) and trifluoroethanol (TFE), complexed with 2,4,6-tri--butylpyrimidine (TTBP) were explored, revealing the essential role of the close accompanying base for rendering glycosidic bond formation thermodynamically favorable. Our work deepens the comprehension of the glycosylation mechanism, paving the way for the rational design and future advancement of efficient and environmentally friendly stereoselective glycosylation reactions.","PeriodicalId":12794,"journal":{"name":"Green Synthesis and Catalysis","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140148065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The esterification of DHP and AA achieved a 59.8% DHP conversion and 91.2% tetrahydropyran-2-yl acetate selectivity (THPOAc) at 373 K for 1 h and DHP/AA molar ratio of 1 without catalyst.
